If aimed at me, and understandably, I plead guilty!
I inferred that the plot of Gray Matter is more appealing to women than to the vast majority of men. Several other posts & comment etc. on the Net imply the same thing.
This doesn't negate JJ's excellent storytelling!
BTW – being a Physics person, I do not believe in so called supernatural phenomena – but our 'heroine' Sam doesn’t either! So I'm in good company – and no insult intended.
In any case, I believe that one of the main motif's of the plot was to contrast the supernatural with materialistic hoodwinking 'magic'. Hence the name of Sam's pet rabbit! Houdini in later life set about debunking all the hoaxes and frauds who purported to spread séances & other such phenomena.
This caused a rift between him and his friend Conan Doyle who desperately wanted to contact his dead son and others of his family through `spiritualism.
P.S.
I love
ALL the works of Jane Austen!
